Note: 1. Valid for Ambient Operating Temperature: T
A
= –40 to 85°C; V
CC
= V
RST
(max) to 5.5V; and V
BAT
= 2.8V (except where noted).
2. V
CC
supply current, logic input leakage, Watchdog functionality, Push-button Reset functionality, PFI functionality, state of RST and
RST tested at V
BAT
= 3.6V, and V
CC
= 5.5V. The state of RST or RST and PFO is tested at V
CC
= V
CC
(min). Either V
CC
or V
BAT
can go to 0V if the other is greater than 2.0V.
3. V
CC
(min) = 1.0V for T
A
= 0°C to +85°C.
4. Tested at V
BAT
= 3.6V, V
CC
= 3.5V and 0V.
5. Guaranteed by design.
6. The leakage current measured on the RST pin (STM804/805) or RST pin (STM795) is tested with the reset output not asserted
(output high impedance).
7. Not valid for STM795/804/805 (open drain).
8. When V
BAT
> V
CC
> V
SW
, V
OUT
remains connected to V
CC
until V
CC
drops below V
SW
.
9. When V
SW
> V
CC
> V
BAT
, V
OUT
remains connected to V
CC
until V
CC
drops below the battery voltage (V
BAT
) – 75mV.
10. The reset threshold tolerance is wider for V
CC
rising than for V
CC
falling due to the 10mV (typ) hysteresis, which prevents internal
oscillation.
